When talking to a fellow camper who had one, he said you set it for the state your in by using the states abriviation such as FL for Florida and it will auto aim. Now the problem I see is Dish is not authorized to provide service in Mexico. If you wern't to far south you could probably set it to the US state to your north and get it to work, as the coverage area would probably be large enough to work. On the other hand, it may just find the sat and work. Just trying to give you something to think about.

We had to buy a 32" dish to get reception in San Carlos - it worked there and worked as far south as Mazatlan but got harder and harder as we went further south - nothing south of Mazatlan. The further you go the larger dish you need. A guy in Playa del Carmen said he would set us up with a 48" dish but wanted something like $800 US. We see people with dishes from Canada but only for Canadian TV. A small dish will not get you very far in Mexico - don't know about Kino or Penasco. A few years ago we took a route down through Chihuahua and were able to get US TV about as far as there with our dome but beyond that nothing.
